An Investigation on the Value-Based Evaluation: Optimum Rehabilitation Process of the Unreinforced Masonry Buildings

Abstract eng:
Nowadays, distinctive methods are being used for evaluation of alternatives in making-decision. Among them the analytic hierarchy process (AHP) is one of the most efficient one. The study is set up for the low-rise unreinforced masonry buildings and includes classification of the most important parameters in strengthening of masonry buildings, and the factor analysis is performed to make the preferences of the alternatives. Due to the existence of the large number of unreinforced masonry buildings, and also the great importance of process duration for clients, the application of the AHP method in order to optimize the process and reach to the best alternative of the masonry buildings strengthening are developed. Effective parameters in evaluation of the alternatives are classified and suitable alternatives for rehabilitation are evaluated. Finally, based on the binary concept the model of binary approach decision-making (BADM) is utilized to analyze the decision parameters. Therefore, each criterion is simulated by question texts which appraiser faces two possible answers; yes and no. The results illustrate preference of the strengthening the masonry walls with interior shear wall, compared to the other alternatives. Also, effectiveness of the method is compared to the expert judgment.
